Brian likes to go bird watching along the Harvest Park Trail in a nearby forest preserve. He wants to calculate the area enclose
QveST [7]

The question has missing details

The m<em>issing options are: </em>

<em>A. 188,000 square yards </em>

<em>B. 138,000 square yards </em>

<em>C. 600 square yards </em>

<em>D. 300 square yards</em>

<em>See attachment 1 for the missing diagram</em>

Answer:

<em>B. 138,000 square yards </em>

Step-by-step explanation:

The figure can be divided into two shapes (see attachment 2)

From attachment 2,

The dimension of the big rectangle is 1300ft by 800ft

The dimension of the small rectangle is 500ft by 400ft

So, the area is:

Area of the big rectangle added to the area of the small rectangle

i.e.

Area = 1300 * 800 + 500 * 400

Area = 1040000 + 200000

Area = 1240000ft^2

Convert to yd^2 by dividing by 9

Area = 1240000yd^2 /9

Area = 137777.777778\ yd^2

<em>From the list of given options, the closest to the area of the diagram is </em>

<em>B. 138,000 square yards  </em>

kari74 [83]

Answer: green = 25/100, red = 1/100

Step-by-step explanation: add ALL of the gumballs, there's your denominator, now you have 0/100 (1+74+25), count the amount of marbles you want to get the probability of, lets say green, there's your numerator (25) = 25/100
